pairs HENRY EWOLDT, OF GRAND ISLAND, NEBRASKA.

To all whom it may concern.

Be it known that I, HENRY EwoLnT, a citizen of the United States,residing at Grand Island, in the county of Hall and State of Nebraska,have invented certain new and useful Improvements in Band-Cutters andFeeders, of which the following is a specification.

My present invention relates particularly to band cutters and feedersfor threshing machines, my object being to provide certain novel anduseful improvements with respect to the structure of such devices,whereby to promote efliciency.

In the accompanying drawings, which show the details of my invention,Figure 1 is a longitudinal section. Fig. 2 is a side elevation, and,Fig. 3 is a detail of the governor or clutch wheel.

Referring to these figures, the frame 5 supports the usual threshingcylinder 6 and its concave 7, the latter having an upwardly projectingportion 8 (see Fig. 1) extending past the retarder shaft 9, carryingwheels 10, and provided at its upper end with rollers 11 on which theadjacent end of the feed pan 12 moves. This feed pan 12 is swinginglvmounted, by means of sus ended links 13 in the frame 5, between thebefore mentioned portion 8 of the cylinder concave, and the upper end ofthe feed belt or bundle carrier 14, and is given movement by means of anarm 15 eccentrically connected to a shaft 16 having a sprocket wheel 17upon its end. The upper roller of the carrier 14 has a gear wheel 18engaging a gear wheel 19 on a shaft 20 which has a sprocket wheel 21above sprocket wheel 17.

About the sprocket wheels 17 and 21 is trained a sprocket chain 22,extending from the sprocket wheel 23 of the main shaft 24 which carriesa tight wheel 25 and on which is mounted loosely, the governor wheel 26.This governorwheel 26 is provided with an outstanding circular flange 26carrying intermediately pivoted clutch arms 27 having shoes 28 at oneend to engage the shaft wheel 25, and provided at their opposite endswith Specification of Letters Patent.

weights 29 and springs 30 acting in opposition to said weights. As soonas the wheel 26, which is driven from a suitable source of power,attains the required speed, the weighted ends of arms 27 move outwardly,and cause shoes 28 to engage the shaft Wheel 25 and thus rotate shaft24. In like manner when rotation of wheel 26 decreases, springs 30 forcethe shoes 28 away from the shaft Wheel, serving to stop rotation ofshaft 24 and in this manner to check the feed before rotation of thethreshing cylinder 6 ceases as will be hereinafter described.

The frame 31 of the band cutter, has a boxing 32 eccentrically mountedupon the main shaft 24 and is suspended at one end by means of aswinging link 33. Adjacent the opposite end of this frame 31, at 34 arepivoted the knife bars 35, at the opposite ends of which are pivotedadjusting bars 26 adapted to be adjustably connected to the frame 31adjacent link 33. The eccentric boxing imparts an oscillatory movementto the band cutter when the shaft 24 is in motion.

The governor wheel is connected, by a belt 37 to the threshing cylinder6, which belt passes over the wheel 38 at the end of a shaft 39 arrangedin a vertical line above the retarder shaft 9 and connected thereto by abelt 40. On shaft 39 is arranged a tight roller 41 which is squared, andthe sides of which are concaved as shown, the function of this rollerbeing to beat the straw and grain and hold the same down straight towardthe threshing cylinder.

It will be noted that the feed board 8 extends at an acute inclinationtoward the cylinder 6, and that the retarder 10 is located atsubstantially the same level as the top of the cylinder. The beater 41is located slightly in advance of the discharge end of the feed pan 12and also above the same, in close proximity thereto. The purpose of thisarrangement of parts is to prevent the straw from choking the cylinder.The beater holds the bundles down as they leave the band cutter knivesand the feed pan, and they drop down toward the cylinder, and beforereaching the same the straw is thoroughly thinned out by the retarder.

I claim:

In a threshing machine, a feed board eX- tending at an acute inclinationtoward the cylinder, a retarder projecting through the feed board, areciprocating feed pan having its discharge end supported on the upperend of the feed board, a beater located in advance of the discharge endof the feed pan and above the same, in close proximity thereto, and aband cutter located above the feed pan.

In testimony whereof I afiix my signature 15 in presence of twowitnesses.
